I'm not sure about the river but Lake Scugog in port perry had some very decent bass fishing, with my snakes and jigs i caught 4 nice bass(2 on each) I think the weights were 2.8, 2.6, 2.7, and a 3ld'r...witch in my opinion was pretty good for shore fishing in port perry lol. I would love to fish the river!
But i did work for those fish, i had at least six times walking the shores where i would only get a single bite or nothing at all
